Radius Systems' constant torque application benefits from SynRM technology by ABB

Up to 15 percent lower energy use, a significant reduction in motor maintenance costs and a drop in audible noise are achieved with the installation of an ABB synchronous reluctance motor and drive (SynRM) package on a twin extruder application.

Radius Systems’ plant in Derbyshire, UK, houses 14 extrusion lines together with an injection-moulding facility making associated fittings for use by utility companies for gas and water transfer. Eight lines are powered by DC motors, many of which are over 20 years old. However, Line 12 had a particularly high utilization rate and yet the 182 kW DC motor was regularly failing, leading to an increase in downtime and rising maintenance costs. 

ABB’s authorized value provider Inverter Drive Systems (IDS) carried out ‘before’ and ‘after’ monitoring of the DC motor, which estimated that potential energy savings from a SynRM package for Line 12 would be in the range from 8 to 15 percent, with a return on investment within two years. In addition, in excess of £2,000 cost avoidance is estimated with the removal of DC motor maintenance. “SynRM has given us a reduction in noise in the production hall which is a benefit we had not expected,” says Rob Betts, Engineering Manager at Radius Systems.
